The term "Joint learning" (Joint learning) is not a recent term, and in the field of natural language processing, researchers have long used a joint model based on traditional machine learning (Joint model) to learn about some of the closely related natural language processing tasks. For example, entity recognition and entity standardization Joint learning, Word segmentation and POS tagging joint learning and so on. Recently, the research

How CNN applies to NLP
What is convolution and what is convolution neural network is not spoken, Google. Starting with the application of natural language processing (so, how does any of this apply to NLP?).Unlike image pixels, a matrix is used in natural language processing to represent a sentence or a passage as input, and each row of the matrix represents a token, either a word or a character. So each ro

Introduction
Frankly speaking, I can't really understand deep learning for a while. I look at relevant research papers and articles and feel that deep learning is extremely complex. I try to understand neural networks and their variants, but still feel difficult.
Then one day, I decided to start with a step-by-step basis. I break down the steps of technical operations and manually perform these steps (and calcula

Objectivethe first article of the 2017.10.2 Blog Park, Mark. Since the lab was doing NLP and medical-related content, it began to gnaw on the nut of NLP, hoping to learn something. Follow-up will focus on knowledge map, deep reinforcement learning and other content.To get to the point, this article is a introduciton of using neural networks to deal with NLP problems. Hopefully, this article will have a basic concept of natural language processing (usi

ICML 2016 's article [Noisy Activation Functions] gives the definition of an activation function: The activation function is a map h:r→r and is almost everywhere.The main function of the activation function in neural network is to provide the nonlinear modeling ability of the network, if not specifically, the activation function is generally nonlinear function. A
At present, there are neural networks in all aspects of engineering application, and younger brother is now learning neural network, a little conjecture.Most of the current neural network is to adjust their own weights, so as to learn. Under the structure of a certain

In the comprehensive evaluation of customer service perception of information system, it involves a lot of complex phenomena and the interaction of many factors, moreover, there are a lot of fuzzy phenomena and fuzzy concepts in the evaluation. Therefore, in the comprehensive evaluation, some scholars use the method of fuzzy comprehensive evaluation to quantify, evaluate the information System customer service awareness level, and has achieved some results. However, using this method to mo

1. Data preprocessingbefore training the neural network, it is necessary to preprocess the data, and an important preprocessing method is normalization processing. The following is a brief introduction to the principle and method of normalization processing. (1) What is normalization?Data normalization is the mapping of data to [0,1] or [ -1,1] intervals or smaller intervals, such as (0.1,0.9).(2) Why shoul
Why should I introduce an activation function?If you don't have to activate the function (actually equivalent to the excitation function is f (x) =x), in this case you each layer of output is a linear function of the upper input, it is easy to verify that no matter how many layers of your neural network, the output is a linear combination of input, and no hidden layer effect, this is the most primitive perc
This paper, based on the http://en.wikipedia.org/wiki/Backpropagation of Wikipedia, makes a summary of the neural network's back propagation algorithm, and makes a simple formula derivation.A typical post-propagation algorithm for a 3-layer neural network with only 1 hidden layers is as follows:Initialize network weigh
